Circle o is inscribed in the given triangle
Webby using Pythagoras theorem r = 1 LO = 1 2a LM2 = ON2 + r2 at ON2 = 3 therefore LM = 2 since side opposite to 30° half the hypotunes therefore angle ∠MNO = 30° and angle ∠MLO = 30° too! IN triangle LMO angle ∠M = 180° − (30° + 30°) = 120° since angle X half the centric angle therefore angle X = 60° Share Cite Follow edited May 2, 2012 at 19:00 WebGiven: An isosceles ΔABC with AB=AC, circumscribing a circle. To prove: P bisects BC. Proof: AR and AQ are the tangents drawn from an external point A to the circle. Therefore, AR=AQ (Tangents drawn from an external point to the circle are equal) Similarly, BR=BP and CP=CQ. It is given that in ΔABC, AB=AC. ⇒AR+RB=AQ+QC ⇒BR=QC(As AR=AQ)
